A Phase 1/2 Trial of Pembrolizumab in Combination With Blinatumomab in Patients With Relapsed/Refractory Acute Lymphoblastic Leukemia

Description

This phase I/II studies the side effects of pembrolizumab and blinatumomab and to see how well they work in treating participants with acute lymphoblastic leukemia that has come back or has not responded to the treatment. Monoclonal antibodies, such as pembrolizumab and blinatumomab, may interfere with the ability of tumor cells to grow and spread.PRIMARY OBJECTIVES: I. Assess the safety and tolerability of combination immunotherapy with blinatumomab and pembrolizumab by evaluation of toxicities including: type, frequency, severity, attribution, time course and duration. (Phase 1) II. Determine the recommended phase 2 schedule of combination immunotherapy with pembrolizumab and blinatumomab. (Phase 1) III. Evaluate the anti-leukemia activity of combination immunotherapy blinatumomab and pembrolizumab as assessed by overall response rate (complete response \[CR\] or CR with incomplete recovery \[CRi\]). (Phase 2) SECONDARY OBJECTIVES: I. Estimate time to response (CR or CRi) and resp

TKIs are not permitted to be continued at screening (e.g. Gleevec) * Intrathecal (IT) chemotherapy may be dosed up to 7 days prior to first dose of pembrolizumab (cytarabine \[Ara-C\] recommended) * For biologics (e.g. monoclonal antibodies), washout period of 1 month beyond the recommended dosing interval and at least 4 weeks or 5 half-lives (whichever is longer) since the last dose * All acute toxic effects of any prior antitumor therapy must be resolved to grade =\< 1 before enrollment, with the exception of alopecia (any grade permitted), or bone marrow parameters (any grades permitted) * For female subjects of childbearing potential, willingness to abstain from heterosexual intercourse or use 2 concurrent protocol recommended methods of contraception from the screening visit throughout the study treatment period and to 30 days from the last dose of pembrolizumab; a negative serum pregnancy test is required for female subjects at screening; lactating females must agree to discontinue nursing before administration of study drugs * For male subjects having intercourse with females of childbearing potential, willingness to abstain from heterosexual intercourse or use 2 protocol-recommended methods of contraception from the start of pembrolizumab throughout the study treatment period and for 90 days following the last dose of pembrolizumab; also, male subjects should refrain from sperm donation from the start of pembrolizumab throughout the study treatment period and for 3 months following the last dose of study drugs * In the judgment of the investigator, participation in the protocol offers an acceptable benefit-to-risk ratio when considering current disease status, medical condition, and the potential benefits and risks of alternative treatments for the subject's ALL * Willingness to comply with scheduled visits, drug administration plan, imaging studies, laboratory tests, other study procedures, and study restrictions; psychological, social, familial or geographical factors that might preclude adequate study participation should be considered * Have the ability to understand and sign a written informed consent form, which must be obtained prior to initiation of study procedures Exclusion Criteria: * Diagnosis of mature B-cell ALL (Burkitt's leukemia) according to World Health Organization (WHO) classification, or lymphoid blast crisis of chronic myelogenous leukemia (CML) * A life threatening illness, medical condition or organ system dysfunction which, in the investigators' opinion, could compromise the subject's safety or interfere with the absorption or metabolism of pembrolizumab * Active or symptomatic central nervous system (CNS) disease * For study purposes, a subject will not be considered as having active CNS disease if the subject has documentation of prior CNS disease and has received prior treatment (IT or radiation) and is: * Asymptomatic for the last 28 days prior to screening and * Has documented at least 2 negative cerebrospinal fluid (CSF) cytology (which must include 1 lumbar puncture \[LP\] within the study screening window) * Uncontrolled undercurrent illness including but not limited to unstable angina pectoris or psychiatric illness/social situations that would limit compliance with study requirements;
